US 6039 - question regarding lubricating spindle/axle of blower fan

[goode2shoes]

In the online manual for the 6039 concerning end of year maintenance, it states to use spray vegetable oil (Spam or eqivalent) on the fan units.

On my blower fan (on left side of unit) it starts up with a high squeek/squeel. So I used Pam spray on the exposed end of the spindle/shaft in the squirrel cage. It stopped the high pitched noise on the following stove start up. But it reappeared on the next start up after the weekly cleaning.

Here is my question. Why can't I use WD-40 or 3 in 1 Oil on the spindle/shaft???

Any ideas?

Smell issues coming through the blower, I would try just a bit of 3 in 1 and see if you smell it...

I never thought about a smell issue. But I'm really tired of spraying Pam everytime I do my weekly/bags burnt cleaning !!

I'm going to give it a try.
